I am responding to Dafo, of Telefomin.
Where in the Bible is it mentioned that the Sabbath falls on either a Sunday or Saturday? I bet there is nothing. Instead the Bible simply refers to the first day of the week.
You and I were not around when the calendar was created and the days were named.
You are telling Christians to worship on the Saturday as if you were there when the days were created and named.
Remember that no one on Earth is so perfect as to be able to judge another person.
What is important is worshipping God. On which day you do that in does not matter.
